I don't think astro would suit this lens (not wide enough?) but since it has a very interesting bokeh I would often place my subject relatively off-centre and trying to have it sharp(ish) while still trying to isolate them from the background. That is mostly the reason I often use manual focus: to have control over what I see and what I get (unlike with native AF lenses that display always at wide-open).Why shoot distant subjects wide open? Astro?
I know what you mean: the adapter is just a tiny bit too short, but it is not the case here.Gnarlydog, are you focussing with the viewfinder or the scale (ie turning the focus ring all the way to the end stop)? It may be your adapter is the problem not the lens. I found that when my lens is wide open and set to focus at infinity using the scale, in fact it has gone beyond that and needs to be brought back slightly to get a sharp image. If I focus with the viewfinder, I can get far away objects sharp even at f1.8.

With the VF-4 (electronic viewfinder) I use x10 magnification to really nail the focus.
very sharp centre but utter rubbish on the edges (very soft/blurry), when at infinity wide open at f1.8.Not sure if it is field curvature either where the lens will focus in a curved field, instead of flat.
I have asked one other person to let me know his findings with his lens and he confirmed his copy does the same...
can I assume the second image was taken with the aperture wide open?
At least this is how my copy of the 38mm f1.8 renders at distant focus, with a lot of distortion, soft image and glow
OK, now I understand that this lens has maybe a bit more cult status than it should, at least for my styleYup. At f1.8 it is a bit, ahem, gnarly. I usually try and stay at f2. But I have also have a Jupiter8 50/2 and I've learned it's best not to go wider than f2.5 with that.
